Definitions

  • This invention relates to a bale wrapper with a tiltable turntable to permit loading and unloading of a cylindrical bale of straw or hay.
  • bale wrapper which is used to wrap a continuously supplied stretchable sheet of plastics film around a bale which is supported on spaced-apart rollers on a turntable, and which bale is rotated about its axis as the sheet is wrapped around it. This causes a substantially air-tight wrapping to be formed which envelopes the bale, and protects the bale from the weather so that outside storage is possible without any appreciable deterioration in the nutritional properties of the bale material.
  • Bale wrappers are used to wrap "big bales" of straw, and also hay, and in the latter case, by virtue of the tight wrapping which is possible, the hay can be allowed to mature to form hay silage over a period of time during storage in its wrapping.
  • the entire outer periphery of the bale is covered with the sheet of stretchable material by reason of the fact that the bale is rotated both about a horizontal axis by the rollers of the turntable, and also about a vertical axis by rotation of the entire turntable and bale about this vertical axis.
  • the sheet of stretchable film is therefore supplied from a dispenser reel mounted at a fixed position on the framework of the bale wrapper.
  • bale wrappers There are type main types of bale wrapper in use at the present time, namely mobile bale wrappers which can be trailed behind a tractor to be used in a field, and bale wrappers which will be used at a fixed location e.g. in a stackyard.
  • trailed bale wrapper such as the Silawrap bale wrapper made by Underhaug
  • Silawrap bale wrapper made by Underhaug
  • the mechanism can then be operated to raise the bale from the ground and to deposit it onto the turntable. Wrapping of the bale then takes place, followed by rearward tilting of the turntable in order to deposit the wrapped bale on the ground.
  • the Silowrap bale wrapper is protected by British Patent No 2159489B, and equivalent foreign patents, and to which reference may be made for a fuller disclosure of the construction and operation of rotatable turntable type bale wrappers with fixed film reels (there are other versions of bale wrapper in which the bale is rotated about its own axis, while a film dispenser is caused to orbit in a horizontal plane around the rotating bale).
  • bale wrapper and particularly stationary bale wrappers, which rely upon the use of a separate piece of equipment to load unwrapped bales onto the turntable, such as a fork lift arrangement or a spike mounted on a tractor.
  • the present invention is concerned with a rotating turntable type of bale wrapper and which is capable of loading an unwrapped bale onto the turntable, and to unload the bale from the turntable after wrapping, without the need for any separate piece of bale handling equipment.
  • a round-­bale wrapper apparatus which is capable of being mounted on or attached to a tractor and which comprises: a main frame which is securable or attachable to the tractor; a sub-frame adjustably mounted on the main frame for movement between a bale-wrapping position and a tipped position; a turntable mounted on the sub-frame and adapted to receive a round bale thereon, said turntable being operative when the sub-frame is in its bale-wrapping position to rotate the bale about its axis, and the turntable itself with the bale thereon also being rotatable about a substantially vertical axis; means for mounting a film dispenser reel on one of said frames, whereby in service film can be withdrawn from the reel to be attached to the bale and upon rotation of the bale about its axis and rotation of the turntable the film can be automatically wrapped around the bale; and, a pick-up mechanism mounted on the sub-frame and operative, when the sub-frame is moved to its tipped
  • bale wrapper is able to carry out usual bale wrapping operations once the apparatus itself has lifted the bale onto the turntable.
  • the bale wrapper apparatus is therefore particularly useful in the stackyard where wrapped bales are to be stored, though of course the bale wrapper apparatus may be used as a mobile installation operative on bales as they are deposited by a baler in the field.
  • the pick-up mechanism may comprise an arm pivotally mounted on an upstanding portion of the sub-frame and having a transverse bale-engaging member at its free end, the arm being movable between a bale-receiving position and a bale-holding position. Then, upon tipping of the sub-­frame and with the arm in its bale-receiving position, the arm can be lowered over and partly around the bale, and upon movement of the arm to its holding position, the arm can move and then hold the bale against the turntable.
  • the arm may be pivoted between its two positions by a ram or other suitable arrangement.
  • the pick-up mechanism may comprise a cradle which can fit over and around a bale, such cradle being pivotally mounted on the sub-frame in similar manner as the pick-up arm just referred to.
  • bale Once a bale has been wrapped, it can then be unloaded using the pick-up mechanism to hold the wrapped bale while the turntable is tipped, and then release of the wrapped bale by the pick-up mechanism will allow the bale to roll gently under gravity onto the ground, or onto any stacked position.
  • the main frame may be a wheel-supported frame, if it should be desired to provide a bale wrapper apparatus which can be towed behind a tractor.
  • the main frame has suitable rigid mounting points which will enable the main frame to be coupled rigidly to the usual three point hitch at the rear of a tractor, or to be front mounted on the tractor e.g. by attachment to a front mounted lift arm arrangement.
  • the entire bale wrapper apparatus can be raised with a wrapped bale thereon, and then following tilting of the sub-frame the wrapped bale can roll under gravity onto the top of a growing stack of wrapped bales.
  • a stand for mounting a film reel dispenser is carried by the main frame, and therefore the reel will not be tilted (and risk falling off its mounting) when the sub-frame is tilted.
  • An automatically acting cutter arrangement may be provided to cut the length of film running between a wrapped bale and the reel when the sub-­frame is tilted.
  • the turntable may comprise laterally spaced and parallel rollers onto which a round bale can be supported for rotation, and at least one of the rollers may have a brake mechanism operative to brake the roller when the sub-­frame is tilted and thereby control the tendency for the wrapped bale to roll-off the turntable prematurely as the sub-frame commences its tilting movement.
  • the turntable may have a ring gear drive mechanism operative to rotate the turntable about its vertical axis, and preferably the arrangement will be such that the turntable is lined-up with the axes of the rollers extending substantially perpendicular to the general longitudinal axis of the tractor.
  • the sub-frame can then load or unload a bale by moving the bale in a direction along this axis, and this therefore enables the driver of the tractor readily to view the progress of the operation.
  • a spring-loaded latch mechanism may be provided to engage the ring gear and thereby hold the turntable in a required predetermined attitude about its axis of rotation while the sub-frame is tipped, and this mechanism may be automatically disabled as the sub-frame returns to its bale-receiving position by engagement with an actuator pad or the like on the main frame with a pivot arm of the latch mechanism.
  • a round-bale wrapper apparatus is capable of being mounted on or attached to a tractor, and may be provided with a turntable of known construction which is capable of receiving a round bale thereon, and which is operative to rotate the bale about its axis while the turntable itself with the bale thereon is rotated about a substantially vertical axis.
  • the turntable and roller design may be in accordance with that known from the Silawrap machine made by Underhaug, and as disclosed, for example, in more detail in British Patent No 2159489B.
  • a film dispenser reel is mounted on the apparatus, and in service the film can be withdrawn from the reel to be attached to the bale, and upon rotation of the bale about its axis and rotation of the turntable about its axis, the film can be automatically wrapped around the bale.
  • the apparatus 10 has a main frame 11 which is securable to a rear mounted three point hitch 12 of a tractor, as shown in Figure 3, or which may be rigidly mounted at the front of a tractor, as shown in Figure 5, at the front ends of hydraulically operated lift arms 13.
  • a sub-frame 14 is adjustably mounted on the main frame 11 for movement between a bale-wrapping position, as shown in Figure 3, and a tipped position as shown in Figure 1.
  • a ram 15 interconnects the main frame 11 and sub-frame 15, and is operative to tilt the sub-frame 14 between its two positions.
  • a turntable 16 having spaced apart rollers 17 is mounted on the sub-frame 14, and is operative when the sub-­frame is in the bale wrapping position shown in Figure 3 to rotate a round bale 18 about its own axis while the turntable itself with the bale thereon is rotated about a substantially vertical axis 19.
  • a film dispenser reel 20 is mounted on one of the frames which, in the illustrated embodiment, will be the main frame 11, via a suitable support 21, and a length of film can be withdrawn from the reel to engage the bale 18, when in the position shown in Figure 3, to enable bale wrapping to take place.
  • a pick-up mechanism designated generally by reference 22 is mounted on the sub-frame 14 and is operative, when the sub-frame 14 is moved to its tipped position shown in Figure 1, to engage the bale 18 lying on the ground and to move the bale into engagement with the turntable 16 and to hold the bale on the turntable as the sub-frame 14 is moved to its horizontal bale-wrapping position shown in Figure 3.
  • the pick-up mechanism 22 in the embodiment of Figures 1 to 5 comprises an arm 23 which is pivotally mounted via a pivot 24 on an upstanding portion 25 of the sub-frame 14, and a ram 26 is operative to pivot the arm 23 between an open bale receiving and release position, as shown in Figure 3, and a bale-holding position as shown in Figures 1 and 2.
  • the arm 23 can be lowered over and partly around the bale.
  • the bale when in the position shown in Figure 3, it can then be unloaded using the pick-­up arm 23 to hold the wrapped bale initially while the turntable 14 is tipped, and then release of the wrapped bale by the arm 23 can allow the wrapped bale to roll gently under gravity onto the ground, or onto a stack, as shown in Figure 5.
  • the illustrated embodiment is designed to be rigidly mounted behind or in front of a tractor, via suitable rigid mounting points provided on the main frame, though the main frame may be a wheel supported frame, if it should be desired to provide a bale wrapper apparatus which can be towed behind a tractor.
  • the film dispenser reel 21 is mounted on a stand carried by support 21, and therefore the reel is not tilted when the sub-frame 14 is moved to its tilted position.
  • An automatically acting cutter arrangement (not shown) may be provided to cut the length of film running between a wrapped bale and the reel 20 whenever the sub-frame is tilted.
  • the turntable rollers 17 are laterally spaced apart from each other and extend parallel to each other, and at least one of these rollers may have a brake mechanism operative to brake the roller when the sub-frame is tilted and thereby to control any tendency for a wrapped bale to roll off the turntable 16 prematurely as the sub-frame is tilted.
  • a ring gear drive mechanims shown schematically by reference 28, is operative to rotate the turntable 16 about a substantially vertical axis, when in the bale wrapping position shown in Figure 3, and the turntable will normally be lined-up with the axes of the rollers 17 extending perpendicular to the general longitudinal axis of the tracvtor, whereby the sub-frame can load and unload a bale by moving the bale in a direction along this axis, which will enable the driver of the tractor readily to view the progress of the operation.
  • a spring loaded latch mechanism may be provided (not shown) to engage the ring gear 28 and thereby hold the turntable in any required predetermined attitude while the sub-frame 14 is tipped, and this mechanism may be automatically disabled as the sub-frame 14 is returned to its bale-wrapping position by engagement with an actuator pad 29 (see Figure 2) on the main frame 11 which engages with a pivot arm of the latch mechanism.
  • FIG. 1 to 5 has a pick-up mechanism which comprises a single pick-up arm 23, as shown in Figure 4, but an alternative embodiment is shown in Figures 6 to 10, in which an alternative arrangement of pick-up mechanism is provided.
  • Other components of the apparatus correspond with those described above for the first embodiment, and are designated by the same reference numerals, and will not be described in detail again.
  • the second embodiment has a pick-up mechanism designated generally by reference 30, and which comprises a U-shaped cradle 31 which can engage around and hold captive the upper portion of a bale 18, as will be evident from Figures 6 to 10. This may provide additional security against the heavy bale coming out of engagement with the pick-up mechanism, or the turntable, in the event that the bale wrapper apparatus, or a bale to be loaded and unloaded, is lying on uneven ground.
